The Tanoi BSP Tap with oxide finish offers precise, reliable threading for British Standard Pipe connections. Built for professionals and serious hobbyists, it delivers strong performance across a range of materials using a 1/8x28 size.
- Thread Standard: British Standard Pipe (BSP) compatibility to ensure accurate BSP threads and proper fitting engagement.
- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness, wear resistance, and heat tolerance during demanding taps.
- Flute Design: Spiral flute geometry for efficient chip evacuation and reduced risk of binding during deep or fast threading.
- Size & Pitch: 1/8" nominal size with 28 TPI (1/8x28) tailored for BSP male threads in common small-diameter applications.
- Finish: Oxide-coated surface adds wear resistance and smoother cutting action for extended tool life.
- Material Compatibility: Suitable for a broad range of materials, enabling versatile use in metalworking and fabrication projects.
This BSP spiral tap is designed to deliver clean, compliant threads with minimal rework. The cobalt-infused HSS-E substrate maintains cutting performance under heat, while the spiral flute design keeps chips moving away from the cutting edge—helping prevent jams and extend tool life. Ideal for plumbing, machinery assembly, and maintenance tasks that require dependable BSP threading, it’s a strong choice for machinists, technicians, and serious DIYers who demand consistent results from their tapping tools.
